I have an event that changes the Tag associated with my NDrawingDocument, but when I undo the Event it doesn't revert the Tag to it's previous state. Is there something I am missing?

I ask because I have Shapes that are utilizing this behavior properly using the NShape.Drawing.StartTransaction/HistoryService.Commit paradigm.

Is there something I should be doing differently?

Here is my code snippet.


_form.document.StartTransaction("UpdateFormatProperties");
_form.document.Tag = object.Clone();
//Do some other stuff to the document.
_form.document.HistoryService.Commit();

Hi Steve,

Yes indeed this appears to be a bug in the diagram, because the Tag property setter of NDocument (base for NDrawingDocument and NLibraryDocument) is actually not recording the property change. The fix will appear in the next service pack or release.
